我正在看这个matplotlib散点图示例: https://matplotlib.org/examples/shapes_and_collections/scatter_demo.html
"""
Simple demo of a scatter plot.
"""
import numpy as np
import matplotlib.pyplot as plt
N = 50
x = np.random.rand(N)
y = np.random.rand(N)
colors = np.random.rand(N)
area = np.pi * (15 * np.random.rand(N))**2 # 0 to 15 point radii
plt.scatter(x, y, s=area, c=colors, alpha=0.5)
plt.show()
我试图通过利用matplotlib来完成同样的事情:
import numpy as np
import matplotlib.pyplot as plt
from bokeh.plotting import output_file, show
from bokeh import mpl
N = 50
x = np.random.rand(N)
y = np.random.rand(N)
colors = np.random.rand(N)
area = np.pi * (15 * np.random.rand(N))**2 # 0 to 15 point radii
plt.scatter(x, y, s=area, c=colors, alpha=0.5)
output_file("scatter_demo.html")
show(mpl.to_bokeh())
如何调整圆圈的半径?我确信它可以用纯粹的散景完成,但我希望用Bokeh做一个更高级的情节,它依赖于Matplotlib,所以我希望使用show(mpl.to_bokeh())
。谢谢!
在运行Bokeh脚本时,我也收到此警告:
/Users/tc9/lib/python3.6/site-packages/bokeh/core/compat/bokeh_renderer.py:263: UserWarning: Path marker shapes currently not handled, defaulting to Circle
warnings.warn("Path marker shapes currently not handled, defaulting to Circle")

编辑:散点图的等效Bokeh演示示例如下: http://bokeh.pydata.org/en/latest/docs/gallery/color_scatter.html
答案 0 :(得分:2)
我不得不告诉你,截至Bokeh 0.12.5
(将于本周晚些时候发布),Bokeh的MPL compat支持正在被完全弃用。它将在Bokeh 1.0时完全删除,并且在中间时间内不会收到任何更新(所有与其相关的示例和文档也将被删除)。
未来,严格的标准化MPL JSON标准可能会使新的单独项目以可维护的方式提供此功能。
